An earphone case for storing and charging Bluetooth (BT) earphones includes: an earphone container for accommodating a pair of BT earphones; a BT circuit for communicating with the pair of BT earphones through BT communication after the pair of BT earphones is taken out; a microphone for receiving outside sound to generate a microphone signal after the pair of BT earphones is taken out; an audio circuit for generating an audio signal according to the microphone signal and providing the audio signal for the pair of BT earphones through the BT circuit in a predetermined mode; a user interface for generating a control signal according to user control after the pair of BT earphones is taken out, and providing the control signal for the pair of BT earphones through the BT circuit; and a control circuit for controlling the interaction between the earphone case and the pair of BT earphones.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The BT earphone system of claim 1, wherein the user interface circuit includes one of following: a physical button; a touch pad; a touch panel; and a motion detector.
5. The BT earphone system of claim 4, wherein the ID data of the BT circuit is a media access control (MAC) address of the BT circuit, and the ID data of the pair of BT earphones is a MAC address of the pair of BT earphones.
7. The BT earphone system of claim 3, wherein after the pair of BT earphone is taken out from the earphone container, the BT circuit wirelessly connects with the pair of BT earphones to have the pair of BT earphones be controlled by the earphone case.
8. The BT earphone system of claim 3, wherein after the pair of BT earphones is taken out from the earphone container, the pair of BT earphone wirelessly connects with the BT circuit and further with another BT device.
9. The BT earphone system of claim 8, wherein the pair of BT earphones communicates with the BT circuit and the another BT device in a manner of time-division multiplexing.
10. The BT earphone system of claim 1, wherein when the earphone container accommodates the pair of BT earphones, the pair of BT earphones communicates with the earphone case in compliance with one of following protocols: a Universal Asynchronous Receiver/Transmitter (UART) protocol; an Inter-Integrated Circuit (I2C) protocol; and a Serial Peripheral Interface (SPI) protocol.
15. The earphone case of claim 14, wherein the ID data of the BT circuit is a media access control (MAC) address of the BT circuit, and the ID data of the pair of BT earphones is a MAC address of the pair of BT earphones.
17. The earphone case of claim 13, wherein after the pair of BT earphone is taken out from the earphone container, the BT circuit wirelessly connects with the pair of BT earphones to have the pair of BT earphones be controlled by the earphone case.
18. The earphone case of claim 11, wherein the earphone case is configured to communicate with the pair of BT earphones through the multiple case terminals when the earphone container accommodates the pair of BT earphones.
19. The earphone case of claim 18, wherein when the earphone container accommodates the pair of BT earphones, the earphone case communicates with the pair of BT earphones in compliance with one of following protocols: a Universal Asynchronous Receiver/Transmitter (UART) protocol; an Inter-Integrated Circuit (I2C) protocol; and a Serial Peripheral Interface (SPI) protocol.
